Sir, here I filtered grayimage using mean,median,gaussian,wiener filter but i dont know how to measure filtered results. In one research paper filtered result were mea-sured by calculating their TV values, so my question is how to calculate TV values. the following table specifies TV values those are from reserach paper.
Before Filtering After filtering
Median Mean Wiener Gaussian
TV 2403.0 1121.0 1315.2 1124.3 1607.3
Table3.1: TV values comparison
filtered results were further mea-sured by calculating their TV
